The star has been keeping her fans updated with her progress via Facebook, sharing photos, memes and videos throughout her journey.

Earlier this week she shared a snap of a loved one.

"Fevers, a-fib, no food or water since last Tuesday, quite a bit of pain and a lot of fatigue today," she captioned the shot.

"I'm finally 'comfortable' so I'm gonna get some sleep while the going is good. Here is the view I get to drift off with. Anyone who knows me already knows how much I love this man. Didn't know if loving him any more than I already did was even possible. It is...#fckcancer #godsgotthis #bravethestorm."

Following Bey's post, Tiff took to Facebook to thank her for the support.
